Pytorch nn.linear 权重初始化
WebOct 28, 2024 · Newer versions of PyTorch allows nn.Linear to accept N-D input tensor, the only constraint is that the last dimension of the input tensor will equal in_features of the linear layer. The linear transformation is then applied on the last dimension of the tensor. For instance, if in_features=5 and out_features=10 and the input tensor x has dimensions …
